3 The Virtual Video Test Driver (vivid)
6 This driver emulates video4linux hardware of various types: video capture, video
13 Each input can be a webcam, TV capture device, S-Video capture device or an HDMI
14 capture device. Each output can be an S-Video output device or an HDMI output
29 - Support for various pixel aspect ratios and video aspect ratios
45 By default the driver will create a single instance that has a video capture
46 device with webcam, TV, S-Video and HDMI inputs, a video output device with
47 S-Video and HDMI outputs, one vbi capture device, one vbi output device, one
50 The number of instances, devices, video inputs and outputs and their types are
64 - bit 0: Video Capture node
68 - bit 8: Video Output node
73 So to create four instances, the first two with just one video capture
74 device, the second two with just one video output device you would pass
84 are created for each video capture device. At most 16 inputs can be created,
97 - 10: this is an S-Video input
100 So to create a video capture device with 8 inputs where input 0 is a TV
101 tuner, inputs 1-3 are S-Video inputs and inputs 4-7 are HDMI inputs you
111 are created for each video output device. At most 16 outputs can be
122 - 0: this is an S-Video output
125 So to create a video output device with 8 outputs where outputs 0-3 are
126 S-Video outputs and outputs 4-7 are HDMI outputs you would use the
135 give the desired videoX start number for each video capture device.
137 you to map capture video nodes to specific videoX device nodes. Example:
143 This will attempt to assign /dev/video2 for the video capture device of
150 give the desired videoX start number for each video output device.
180 specify the allowed video capture crop/compose/scaling combination
181 for each driver instance. Video capture devices can have any combination
212 specify the allowed video output crop/compose/scaling combination
213 for each driver instance. Video output devices can have any combination
282 Video Capture
285 This is probably the most frequently used feature. The video capture device
288 four inputs are configured: a webcam, a TV tuner, an S-Video and an HDMI
314 TV and S-Video Inputs
317 The only difference between the TV and S-Video input is that the TV has a
340 The initially selected colorspace when you switch to the TV or S-Video input
343 The pixel aspect ratio will depend on the TV standard. The video aspect ratio
345 Choices are '4x3', '16x9' which will give letterboxed widescreen video and
347 video that will need to be scaled accordingly.
388 The video aspect ratio can be selected through the 'DV Timings Aspect Ratio'
391 result in pillarboxed or letterboxed video.
404 Video Output
407 The video output device can be configured by using the module options
409 information), but by default two outputs are configured: an S-Video and an
413 Like with video capture the framerate is also exact in the long term.
416 S-Video Output
420 The S-Video output supports all TV standards.
424 The initially selected colorspace when you switch to the TV or S-Video input
460 it will generate the Wide Screen Signal which is based on the actual Video
463 The VBI device will only work for the S-Video and TV inputs, it will give

569 User Controls - Video Capture
572 The following controls are specific to video capture.
576 video input has its own brightness value, so changing input will restore
577 the brightness for that input. In addition, each video input uses a different

659 does the same for the EAV (End of Active Video) code.
665 These controls are all specific to video capture.
682 S-Video input should be 4x3, 16x9 or anamorphic widescreen. This may
739 be limited or full range. This combines with the Digital Video 'Rx RGB

1053 Video, VBI and RDS Looping
1056 The vivid driver supports looping of video output to video input, VBI output
1057 to VBI input and RDS output to RDS input. For video/VBI looping this emulates
1058 as if a cable was hooked up between the output and input connector. So video
1059 and VBI looping is only supported between S-Video and HDMI inputs and outputs.
1060 VBI is only valid for S-Video as it makes no sense for HDMI.
1070 Video and Sliced VBI looping argument
1073 The way to enable video/VBI looping is currently fairly crude. A 'Loop Video'
1074 control is available in the "Vivid" control class of the video
1075 capture and VBI capture devices. When checked the video looping will be enabled.
1076 Once enabled any video S-Video or HDMI input will show a static test pattern
1077 until the video output has started. At that time the video output will be
1078 looped to the video input provided that:
1081 video from the S-Video output.
1083 - the video resolution of the video input must match that of the video output.
1084 So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz
1085 (720x480) S-Video input, or a 720p60 HDMI output to a 1080p30 input.
1093 Bottom' when the output video is set to 'Field Alternate'. This combination,
1104 - on the input side the "Standard Signal Mode" for the S-Video input or the
1106 valid signal is passed to the video input.
1110 By default you will see the OSD text superimposed on top of the looped video.
1111 This can be turned off by changing the "OSD Text Mode" control of the video
1147 only applies to the TV/S-Video/HDMI inputs and outputs. The reason is that
1190 Video output will also honor any data_offset that the application set.

1234 $ v4l2-ctl -d0 --set-fmt-video=pixelformat='AR15'
1235 $ v4l2-ctl -d1 --set-fmt-video-out=pixelformat='AR15'
1236 $ v4l2-ctl -d2 --set-fmt-video=pixelformat='AR15'

1290 capabilities will slow down the video loop considerably as a lot of checks have
1320 - Some support for testing compressed video
1323 - Fix sequence/field numbering when looping of video with alternate fields
1324 - Add support for V4L2_CID_BG_COLOR for video outputs
